Re: The Phoenix Hand (previously Eagle Hand) fabrication and mechanical function testing

I have finally printed the 130% hand for the testing. Everything printed, and assembled very well. I used 3/8" bands from proximal to palm, and 5/16" bands from proximal to distal phalange, and seemed to work fine. Instructions were clear to me on how this hand goes together I only have a ...

Re: Thermoformed Raptor Reloaded Gauntlet: FEEDBACK/TESTING REQUESTED
